ios - UIBezierPath for Rounding Corner of Button not work properly -


i made class uibutton , override awakefromnib. next (green button) use class.

i have space in right of next button (green one). space more in ipad:

next button

override func awakefromnib() {     super.awakefromnib()      let path = uibezierpath(roundedrect: self.bounds, byroundingcorners: [.topleft, .bottomleft], cornerradii: cgsizemake(5, 5))      let masklayer = cashapelayer()     masklayer.path = path.cgpath     self.layer.mask = masklayer      self.layer.bordercolor = mycolor.nextbuttonborder.cgcolor }

you should put code in 

layoutsubviews()

method. don't forget delete previous added masklayer.

full example: 

override func layoutsubviews() {     super.layoutsubviews()     self.layer.mask = nil     let path = uibezierpath(roundedrect: self.bounds, byroundingcorners: [.topleft, .bottomleft], cornerradii: cgsizemake(5, 5))      let masklayer = cashapelayer()     masklayer.path = path.cgpath     self.layer.mask = masklayer      self.layer.bordercolor = mycolor.nextbuttonborder.cgcolor }

iOS: Performance of reloading UIImage(name:...) -

i have tableview , each row has icon. 90% of rows have same icon. in cellforrowatindexpath method load image assets folder this: var cellimage = uiimage(named: "myimage") does pose performance problem? os somehow smart enough it's same image each time? better if loaded image once , saved in class variable , assigned each time? uiimage 's named: api does kind of caching. if @ uiimage's documentation , states: use init(named:in:compatiblewith:) method (or init(named:) method) create image image asset or image file located in app’s main bundle (or other known bundle). because these methods cache image data automatically, recommended images use frequently.
